- f Application filed July 5, i921. Serial No, 482,450.-

To allwhomit mdg concejrn:

Be it knownthat T, Gnovnn G. PoLsoN,

' a citizen ofthe United States, residing at CIR Berkeley,.in the countyof Alameda and State of Calif rnia, have invented a new. and usefulMultiple-Panel-Locked Cabinet, of which the following is thespecification.

This invention relates to display cabinets."

It is the object of the present invention to provide generally improvedand simplilied form of display cabinet containing a plurality of displaytrays or panels which may be optionally locked either in or out of anaccessible position.

The invention contemplates the use of a cabinet containinga plurality ofdisplay trays or panels which may be shifted from a, concealed positionwithin the-cabinet to an accessible position in. a display opening,

the structure also enibod in a lock meoha nism whereby the panels maybelocked, in

or out of an accessible position within the display opening. V

One form which the invention may as sume is exemplified in the followingdescription and illustrated by way of example in the accompanyingdrawings, inwhich:

Fig. 1. is a front elevation of the preferred embodiment oftheinvention. h Fig. 2 isa vertical section taken 2-2 of Fig. l.

3 is a fragmentary view in perspective of the locking mechanismemployed.

' is aside elevation.

is a plan sectiontakenlon line 5-5 ltetterring more f;articnlarly to thedrawings, generally indicates a cabinet or on line o be g. 5

case of suitable construction and design.

Formed in the front thereof, adjacent one end, is a display opening 11as shown in Fig. l.

Slidably mounted in the cabinet are a plurality of display trays orpanels 12 which are guided for movement longitudinally of the cabinet byguide rails 18 formedin the. cabinet at the top and-.bottom thereot. Theupper and lower ends of the-panels are disposed betweensaid rails asclearly illustrated in Fig, 2. Formed in the lower edge of each displaypanel and thereof is a notch The notch 14: of each panel aligns with alocking pin 15 when the panels are disposed in the position disclosed inFig. 5. These locking pins are secured at one end of a trigger adjacentone end member 16 which is pivotally mounted in the cabinet as at 16 Asshown in "Fig. 1,

the trigger'member is mounted. immediately 1 below a false bottomsection 17 of the cabinet, which false bottom section is apertured as at18 to permit the locking pins 15 to pass therethrough as shown in Fig.'3.

- The trigger member 16 is adapted to be actuated by the keeper of abarrel lock 19. This lock is secured in the end of the cabinet as shownin Fig. l and in a position permi ting the' end 20 of the trigger torest thereon. Therefore, when the keeper of the lock is actuated thetrigger will be rocked on pivot pins 21 and move the locking pins 15 inor out of engagement with the notches 14 as the case may be.

For maintaining the end of the trigger 18 in engagement with the look aspring member 22 is provided. This spring 1s secured to the under sideof the false bottom section 17 and engages the trigger 16 as shownThe'display panels'12 may be equipped with hooks 24 or similar elementsupon which articles to be displayed maybe secured to maintain them inposition on the panels.

In actual practice it has been found that cabinets constructed asdescribed are ex-v tremelyuseful in class rooms or laboratories ofeducational institutions,.where each student is provided with a lockeror compartment. Each ofthe various classes of students meeting in thelaboratory at different periocs may keep their keys on one of thepanels.- As the cabinet may be locked, the

instructor may display each classs panel locked against movement and outof register with the display openingll.

To release the panels a key is inserted in the lock 19 and turned untilthe lock keeper is ejected. This rocks the trigger member 16 asdescribed and removes the locking i the panel shifted into register withthe display opening obstructs the path of said panel and preventsmovement thereof until. the lock ha been actuated.

While I have shown the preferred form oi my invention, it is to beunderstood that rarious changes in the construction, combination andarrangement of parts may be made by those skilled in the art, withoutdeparting from the spirit of the invention a as claimed.

Having thus described my invention, what l claim and desire to, secureby Letters Patent is:

i. A display cabinet comprising a case,

a plurality of display panels mounted in said case, means whereby saidpanels may be shit ed from a concealed position within the cabinet to anaccessible position within the cabinet, and key actuated means forsecuring said panels in a set position.

2. A. display cabinet comprising a case having a display opening formedtherein, a plurality of display panels mounted in said cabinet, meanswhereby aid panels may be shifted from a concealed position within thecabinet intov register withsaid opening, and means adapted to beactuated by a key controlled lock for securing said panels in a setposition.

3. a display cabinet comprising a case having a display openingtormedtherein, a plurality of display panels mounted in said :abinet, meanswhereby said panels may be optionally concealed within said cabinet orplaced in register with said opening, and means adapted to be actuatedby a key controlled lock for locking aid panels in a set position.

i. A dis-play cabinet comprising a case having a display opening formedtherein, a plurality of display panels mounted in said case, meanswhereby said panels may be optionally concealed within the cabinet orplaced in register with said opening, a key actuated lock, and meansactuated thereby and adapted to engage each panel't'or securing the samein a set position.

A display cabinet comprising a case having a display openingv formedtherein, a compartment in said case adjacent said opening, a pluralityof display panels slidably mounted in said case, in a position wherebythey may be placed in register with said opening or concealed withinsaid compartment, a key actuated lock, and a pivotal member actuatedthereby and having locking pins engageable with each of the panels forsecuring the same in a set position.

6. A display cabinet comprising a case having a display opening formedtherein, a compartment in said case adjacent the display opening and incommunication therewith, a plurality oii'rertically disposed panelsslidably i'nounted in the cabinet, guides formed in. the cabinetswhereby the panels may be optionally placed in register with the displayopenin or concealed within said compartment, a recess formed in thebottom oi each panel, a key controlled lock having a keeper, a piyotallymounted trigger member engaging said keeper and adapted to be actuatedthereby, locking pins carried by the keeper and adapted to engage therecesse in the bottom of the panels when said lock is actuated, tomaintain said panels in a set position.
